These reusable metal screw bands for mason jars help seal home canned foods airtight. Screw bands are applied before processing, just until fingertip tight. After processed jars have cooled for 24 hours, the screw bands should be removed and wiped dry; they may then be replaced on the jar, or stored. SNAP lids are sold separately.
